The mystery over McLaren’s line up and why it is taking so long to decide dominated paddock talk in Sao Paulo Thursday.

Asked if he would remain at McLaren, if the offer came, Button said: “I can’t answer that question.

“When you’re put in a position that many drivers have been put in over the years it opens your eyes to different challenges and possibilities, whether it’s racing, doing another sport or something different altogether.

“I’m excited about the challenges ahead. I have a lot of different ideas that I’m excited about for my future, whether it's next year or the year after.

“F1 and motor racing is a massive part of my life and it’s not going to stop. It will continue.

“I just don’t know where that’s going to be right now.

“I never feel like I’m being pushed out of the sport because I’m definitely going to be in the sport in some shape or form and it’s going to be a massive challenge and very exciting.”

Button said it was not even at the top of his list of disappointments.

“There are many things to be disappointed about in sport,” he added.

“If you don’t have a quick car is one. I’m a world champion. I want to win Grands Prix. So if you don’t have a quick car you’re disappointed.

“For me that’s the bit that hurts more than anything else.”

Leading sources at Porsche’s world endurance team flatly deny rumours he has even been in contact.

And with one race left after Sunday’s Brazilian Grand Prix McLaren’s indecision is mystifying.

Although some insist it is linked to Alonso’s move from Maranello.

“It’s a strange situation but you get used to it,” added Button.

“You’re doing what you love. You realise that’s the most important thing, doing my dream job, my hobby. It also something I’m pretty damn good at.

“I’ve had many times in my career where I’ve had issues off the circuit, with contracts.

“If I’m in Formula One next year I’ve got to be winning. That’s what I’m here to do.

“And the past two years haven’t been like that. The first three years at McLaren were amazing. The last two years have been tough.

“Next year if I’m in Formula One I want to be winning races.”

And he insisted his age was no bar to continued competition

“The cars are getting easier to drive, physically. Physically we could all drive with one hand these days.

“It’s not a challenge. The only track that is a challenge is Singapore. It’s got easier and easier over the years.

“I’m also the fittest I’ve ever been right now. My reactions are pretty good, everything is in good shape.”

And Button firmly quashed reports he is retiring from motor racing altogether after the last round in Abu Dhabi.

“I’m not retiring from what I do. I’m a racing driver who has won a world championship who wants to go on and achieve a lot more in motor sport.
